麦秸还田与氮肥运筹对超级稻强弱势粒粒重与品质的影响
Effects of Returning Wheat-residue to Field and Nitrogen Management on Grain Weight and Quality of Superior and Inferior Grains in Super Rice
摘要
Abstract
With the super indica rice Yangliangyou 6 and japonica rice Nanjing 45 as materials, the effects of returning wheat-residue to field and nitrogen management on grain weight and quality of superior and inferior grains were investigated. The results showed that the influence of the two treatments differed among different cultivars and grain positions. Compared with the contrast, the 1000-grain weight (KGW), crude protein content (CPC), breakdown viscosity (BDV) increased under the treatment of returning wheat-residue to field, while the head milled rice rate (HMRR), chalkiness degree (CD), amylose content (AC) and setback viscosity (SBV) reduced. Compared with the basal to tiller fertilizer ratio of 5 : 5, the KGW, CD, AC, BDV increased at the basal to tiller fertilizer ratio of 7 ! 3, while the HMRR, CPC, SBV reduced. The regulatory role in the KGW, HMRR, CD were significantly greater in inferior grains than those in the superior grains. The interaction effects existed between nitrogen management and wheat residue-returning on KGW, HMRR, CPC. Under the treatment of returning wheat-residue to field, the nitrogen application at a basal to tiller fertilizer ratio of 5. 5 : 4. 5 or 6 L 4 could coordinate the formation of the grain weight and quality.关键词
